RESISTANCE MEASUREMENTS

1. Insert RED test lead into V jack
into COM jack
Continuity/Resistance
NOTE: The meter defaults to Continuity testing in this mode. To
enter Resistance testing mode, press the "SEL" button
2. Remove power from circuit.
3. Measure resistance by connecting test leads to circuit. The
meter will auto-range to display the measurement in the most
appropriate range.
NOTE: When in a Resistance setting and the test leads are open
(not connected across a resistor), or when a failed resistor is under
test, the display will indicate O.L. This is normal.
DO NOT attempt to measure resistance on a live circuit.
CONTINUITY
1. Insert RED test lead into V jack
COM jack
Continuity/Resistance
NOTE: The meter defaults to Continuity testing in this mode. Ensure
that the Continuity Testing icon
press the "SEL" button
2. Remove power from circuit.
3. Test for continuity by connecting conductor or circuit with test
leads. If resistance is measured less than 50Ω, an audible signal
will sound and display will show a resistance value indicating
continuity. If circuit is open, display will show "OL".
